invention JEROME C. iBOYLAN, OF'CLEVEIAND HEIGHTS, OHIO led April 4, 1929.

relates to an improvement 1n door operating devices and more particularly t ployed the type of operating devices emconnection with stove oven doors on the ordinary type of ranges.

An object of my door operating device which when invention is to provide a properly installed will not be seen when the oven door is in either open or closed position. It is a further object of my invention to construct this operating device in such a manner that serve partially as a bearing means for the pivoted it will usually frame a he use of secured door so as to thereby elimthe ordinary heavy hinges to the outside of the: stove nd which is more or less unsightly.

Another object of the invention is directed to a means for p cidentally dr object is the reventing the door from acopping open and a still further vision of a means for check- 0 ing the opening movement of the door beyond a predete A still furth provide a doo be neat small 5 same time very will be so located that the space will not be reduced.

er object of my invention is to r operating device which will andin'expensive but at the device which lnterior oven efficient, and a.

As Ia further object of the Adevicethere is providedY means for automatically closing the oven door and `for maintaining it in its closed position until manuallyopened.l

With the objects above indicated and other hereinafter explained in view, my

objects invention consists combination of elements hereinafter described and claimed.

Referring to the drawings:

rangement of the spring and the end of the pivoted arm.

In the drawings, 10/indicates the frame around the door opening of the lower doorof a stove, not shown. with an upper and lower ange 11 and side flanges 12 which extend into the door open'- ing and are of suiiicient width to engage a portion of the door to thereby provide a tight joint and thus prevent the heat from escaping from within the oven.

. At the lower portion of the frame 10 and upon the inner surfa which serves as a portlon of a bearing adapted to receive the extension 14 formed upon the sides and at the lower ends of the door 15.

The door 15 is provi-ded with flanges 15a and 15b which engage with the flanges 11 and 12 of the frame 10 when the door 15'is in closed position.

offset extends inwardly. The upper surface of the offset 16 is provided with a semicircular portion 16a and through this portion extends an opening 17.

A block or casting 20 is located within a cut away portion 15e of the frame 10 and means of a bolt 21. This block or casting 20 is provided with ay recess 200 at its lower portion which .registers with the recess 13 in the frame 10 and they both thereby form a hearing for the extension 14 on the door 15 on the inner side of the frame 10.

The block or casting 20 is further provided with a portion 20d which tits within a recess 19 formed in the ianges 12. In fact the entire lower portion ofthe flange 12 is cut away This frame is providedl An oti'set 16 is formed in to accommodate this block or lcasting 20.

The portion 20d of the casting 2O is'cut off' at right angles to the vertical portions to n form a Hat surface 23 which acts as an abut- A housing 24 is secured to the block or casting 2O by means of bolts 26 which extend through openings provided in the integral flanges 25.A The opening 27 extends entirely through the housing 24 and a slot 28 is provided Which `extends throughout the entire length thereof and communicates' With the opening 27. A rod 32 is screw-threaded into the casting 2() and extends centrally through the opening 27 on the housing 24.

An arm 29 has formed at one end a` rounded head portion 29a which has a central opening 295 Vand a pin 30 extends through this opening 29aand the open-ing`17 in the offset portion 16. The head portion 29ais adapted to fit within the recess 16 so that the outer surface thereof is in the same plane as the outer surface of the iange 150,. The arm 29 is bent inwardly at right angles as indicated at 29e and is provided with-a circular member 31.

The portion 29a' is adapted to slide within the slot 28 and th'e circular member 31 is i adapted to slide within the opening 27 of the housing 24. The arm 29 also extends through the slot 202. -This circular member 31 has a central opening 34 32 and permits the same to slide therein.

A spring 35's interposed between the circular member 31 and the casting 20 and is caused to contract when the door is opened.

The oven Walls, which are not shown, are adapted to be applied in the usual manner and when vso applied completely cover up the device and prevent the heat from coming in contact With it. This is due to the fact that the device is always within an air pocket thereby -contracting the same. 45 P between the Walls of the of the oven.

In operating the device as the door 15 is opened the arm 29 being attached thereto and having thecircular portion 31 formed thereon is caused to engage the spring 35 This spring revents the door 15 from banging open or accidentally flying open aand. as the door reaches its substantially horizontal position the bottom corner of the door 15 engages or abuts the surface 23 formed on the member 2() as indicated at 36 and prevents further open movement thereof.

When it is desired to close the door, it is raised slightly from the horizontal and the springs 35 are of sufficient tension to draw the door into closed position.
